Hair Follicle Drug Testing - Shadybrook, TX

What it is, How it works

Hair screening is recognized as a robust method for identifying drug and alcohol consumption. Hair retains a prolonged record of substance use by embedding biomarkers within the strands as they grow. When samples are taken near the scalp, they can reveal drug and alcohol intake for up to an estimated three months. The collection process for hair is straightforward, relatively resistant to tampering, and easy to transport.

A segment of 1.5 inches, with around 200 hairs (similar to the girth of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the preferred quantity for analyzing and confirming results. To conduct EtG testing, additional assessments, or for procedures surpassing 10 panels, 150mg of hair is advised. It is suggested to measure the hair sample with a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair may be utilized. Head hair refers exclusively to scalp hair, whereas body hair includes all other types (e.g., facial, axillary).

Process Overview

The key phases in labs processing drug test findings include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial entry of a sample into the laboratory’s records. This procedure verifies correct sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any other data entry not handled by an electronic chain of custody protocol.

Screening executes a preliminary rapid examination for substance abuse. While it offers an economical option to rule out drug use in many cases, any positive screenings must be corroborated for legal validity. Samples indicating positive results in Screening necessitate a further validation step.

If results are tentatively positive during Screening, additional hair is taken from the initial sample for the Extraction phase. In this stage, substances are isolated from hair at significantly lower concentrations than with other techniques (e.g., urine or oral fluid), which makes hair drug analysis one of the more challenging methods.

Any positive Screening outcomes are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all potential positive samples are cleaned accordingly. Throughout the entire lab procedure from Accessioning to Confirmation, evaluations adhere to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can indicate drug use over a stretch of up to 90 days, unlike urine tests which capture a shorter usage timeframe.
• Hard to circumvent: Hair drug tests are particularly resistant to tampering, yielding more reliable outcomes.
• Yields usage trend data: They provide insights into drug use history over time, not merely recent consumption.

Limitations:

• Incapable of identifying recent intake: Drugs typically take about 5-7 days to become detectable in hair.
• Expense: Generally, hair drug tests are costlier than other testing methods.
• Result variations: Elements like hair coloration and individual hair growth rates can influence the level of drug metabolites present in hair.

Note: The term "hair follicle tests" is a misnomer as the analyses target the hair strand rather than the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix.
